The use of such a hanger as this in construction work willl tend to stopthe reiiection` and con'-` y adaptable to many other uses -inthebuildingtrade. l

The device will be found suitable and adapted to control soundtransmission between floors andv ceilings, by aA simple and'che'apconstruction.

One form of the invention is illustrated the Vaccompanying `drawing inwhich Fig. l is a perspective View. Fig. 2 isa longitudinal section.Fig. 3 is a longitudinal sect-ionat a right angle to -Althoillustrated acertain way; the parts are capable of being made heavier or lighter `orvaried f to regulate the tension and ,control the vibrations accordingto local conditions.

In the drawing of the'particular form illus# trated 6 indicates "anupperhanger rod or wire which in use will depend fromthe oor or othersupporting structure. This is provided with a resilient material orcomposition. Or itvmay be a.

The metal cover lor washer` l1 fitssomewhat loosely within the top of `the cup, upon theblock of cushioningVmaterial ingout of contact with each other. loop '7 aty its lower4 end,which extends through- `and supports a cup `shaped metal ycasing 8, thebranches of theloop extending through holes in or its equivalent, andthev branches of the loop 7 extend through holes in the washer.

The lower hanger rod or wire is indicatedat 12, and is intended to beattached to the ceiling structure or part to be supported, and thishanger has a loop 13 which extends through the cup, cushion and washerand is looped above the latter.

f The Ycup or casing of cushion material is there- `by conned orinterposed between the upper and lowerhangers in such manneras to form aresilient support and flexible hanger for a ceiling or the like, and theabsence of a continuous metal connection between `the floor and theceiling will serve to prevent the transmission of sound vibrationsthecushion acting to absorb the same. 15

Also, a desirable flexibility is provided, permitting the hangertoaccommodate itself to slight variations in position and vibrationsbetween the supporting and supported structures.

j `Obviously the dimensions of the parts may @e Varied accordingto theloader other factors, and

also the length of the complete hanger `may be` Vvaried accordingtolocal conditions, and it may be used inconjunction with various standardpractices inthe ,construction industry, .and is'25 adaptable to woodjoists, I-beams, concrete, bond-y ing and tying and various other uses.

I claim:` -V ,l 1. A hanger comprising a body of cushioning materialenclosed in a casing, and a pair of oppositely extending wires the endof each of which is bent and coiled upon itself to form a loop extendingyback and forth within the casing and through the cushioningmaterial,the respective loops be- 2. A hanger comprising a cup, a cushionenclosedwithin the cup and resting on the-bottom thereof, a cover on top of thecushion, an upper hanger rod having a continuous loop extending throughthecushion and under the bottom of the cup, and a lower hanger rodhaving a continuous loop extending through the cushion and across overthe cover, said loops being arranged at an angleto cach other.
